Large-Scale Crowdsourcing Subjective Quality Evaluation of Learning-Based Image Coding
Touradj Ebrahimi, Evgeniy Upenik, Michela Testolina
Learning-based image codecs produce different compression artifacts, when compared to the blocking and blurring degradation introduced by conventional image codecs, such as JPEG, JPEG~2000 and HEIC. In this paper, a crowdsourcing based subjective quality e ...
IEEE2021High-Speed ADC Design and Optimization for Wireline Links
The ever-growing global internet traffic has increased demand for higher speed data transmission. As the bandwidth requirements of wireline links increase, extensive digital equalization techniques are required to compensate for the high-frequency channel ...
EPFL2021Benchmarking JPEG XL image compression
Touradj Ebrahimi, Evgeniy Upenik
JPEG XL is a practical, royalty-free codec for scalable web distribution and efficient compression of high-quality photographs. It also includes previews, progressiveness, animation, transparency, high dynamic range, wide color gamut, and high bit depth. U ...
SPIE2020Dissipative dispersion-managed solitons in fiber-optic systems with lumped amplification
We numerically and experimentally studied the shape of the dissipative dispersion-managed solitons (DM-solitons) stably propagating over the lossy DM fiber-optic systems with lumped amplification. We found that, contrary to the lossless case, the chirp-fre ...
OPTICAL SOC AMER2019Cross-Packet Coding for Delay-Constrained Streaming Applications
Dario Floreano, Giuseppe Cocco
Delay-constrained streaming from a moving platform is of paramount importance for applications such as the remote control of drones, where a low-delay video stream is required in order to provide visual feedback to the pilot while providing high quality vi ...
2019Approximate Cloaking via Transformation Optics for Electromagnetic Waves
Cloaking via transformation optics was introduced by Pendry, Schurig, and Smith for the
Maxwell system and Leonhardt in the geometric optics setting. They used a singular change
of variables which blows up a point into a cloaked region. The same transforma ...
EPFL2018Overview of the JPEG XS core coding system subjective evaluations
Touradj Ebrahimi, Irene Viola, Jakub Pospisil, Benoît Macq
The JPEG committee (Joint Photographic Experts Group, formally known as ISO/IEC SC29 WG1) is currently in the process of standardizing JPEG XS, a new interoperable solution for low-latency, lightweight and visually lossless compression of image and video. ...
